Abstract
The utility model provides a submergence depth debugging device for a piano key. The submergence depth debugging device comprises a flat pin bolt and a lower locking door which are arranged on a central disk and a key matched with the flat pin bolt. An adjusting screw is arranged on the central disk between the flat pin bolt and a lower locking door stop. The submergence depth of the key is limited by adjusting the adjusting screw upwards and downwards so that the fussy working procedure of adjusting the submergence depth of the key by increasing or reducing a paper pad and a woolen pad is changed completely; the work becomes easy; and lots of labor can be saved in the production procedure as well as in maintenance and repair procedures. The adjustment of the submergence depth of the key is more precise; the submergence depth is no longer determined by the probable thicknesses of the paper pad and the woolen pad; and the movement distance is controlled precisely the rotation of threads.
Description
Technical field
The utility model relates to a kind of structure of fingerboard.
Background technology
Since piano is born, on the working method of keyboard, continuing traditional technology all the time, promptly available cushioning comes the concordant degree of adjusting key and the submergence depth of key with the way that subtracts pad.In 88 keys, each key all will carry out the process that taking off more than three times loaded onto at least in the piano manufacture process.The spent work in this work of each frame piano is a large amount of, and 30 minutes to 40 minutes time is taken in approximately each debugging work approximately.Under this still more skilled condition, can spend the longer time if not so.If this problem occurs when use, the thing of an expend energy in order to address this problem, is necessary fundamentally to reform especially.
Summary of the invention
It is a kind of easy to adjust that the purpose of this utility model is to provide, the sub-submergence depth debugging apparatus of the piano key that degree of accuracy is high.
The purpose of this utility model is achieved in that and comprises the cotter pilotage nail that is installed in the mid-game, locks a door the key that cooperates with the cotter pilotage nail down; Shelves cotter pilotage nail and the mid-game of locking a door between the shelves down are provided with the adjustment screw.
Characteristics of the present utility model are, come the degree of depth of limit key sinking by the up-down adjustment of adjusting screw, thereby use the plus-minus of paper washer, pad to come the loaded down with trivial details course of work of the sub-submergence depth of adjusting key to be able to thorough change, make this work become light and at one stroke, no matter be in the production run, or maintenance all will save a large amount of work.
The another one characteristics of device of the present utility model are, make the submergence depth adjustment of key more accurate, no longer are to use paper washer, and the general thickness of pad decides submergence depth, but come accurate controlled motion distance with the rotation of screw thread.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
For example the utility model is done more detailed description below in conjunction with accompanying drawing:
The sub-submergence depth debugging apparatus of piano key of the present utility model comprises the cotter pilotage nail 2 that is installed in the mid-game 1, locks a door 3 down, and with the key 4 that the cotter pilotage nail cooperates, shelves cotter pilotage nail is provided with adjustment screw 5 with following mid-game of locking a door between the shelves.
Claims (1)
1. sub-submergence depth debugging apparatus of piano key comprises the cotter pilotage nail that is installed in the mid-game, locks a door down, and the key with the cotter pilotage nail cooperates is characterized in that: shelves cotter pilotage nail and the mid-game of time locking a door between the shelves are provided with the adjustment screw.
